| # Mithril Snapshotter Demo | ||
|
|
||
| **This is a work in progress** :hammer_and_wrench: | ||
|
|
||
| This cli implements a very simple snapshotter of the Cardano Node database for proof of concept only: | ||
| * a **full** snapshot includes `immutable` and latest `legder` state | ||
| * a **light** snapshot includes only `immutable` (the associated ledger state will be recalculated by the Cardano Node at startup) | ||
|
|
||
| --- | ||
| ## Pre-requisites: | ||
|
|
||
| **Install OpenSSL** | ||
|
|
||
| - Install a [correctly configured](https://github.com/openssl/openssl) Open SSL tool (version 1.1.1l+). | ||
|
|
||
|
|
||
| ## Download source code: | ||
| ```bash | ||
| # Download sources from github | ||
| git clone https://github.com/input-output-hk/mithril-proto/mithril-snapshotter-poc | ||
|
|
||
| # Go to sources directory | ||
| cd mithril-snapshotter-poc | ||
| ``` | ||
|
|
||
| ## Run Snapshot and Restore: | ||
| ```bash | ||
| # Run full snapshot of ./testnet.example folder | ||
| # (will be restored to ./testnet.example.restore) | ||
| make snapshot-full src=./testnet.example | ||
|
|
||
| # Run full snapshot of ./testnet.example folder | ||
| # (will be restored to ./custom.restore) | ||
| make snapshot-full src=./testnet.example dest=./custom.restore | ||
|
|
||
| # Run light snapshot of ./testnet.example folder | ||
| # (will be restored to ./custom.restore) | ||
| make snapshot-light src=./testnet.example dest=./custom.restore | ||
|
|
||
| # Run the restored database of the Cardano Node | ||
| # Execute this command in the Cardona Node folder | ||
| ./cardano-node run --database-path=/custom.restore | ||
| ``` | ||
|
|
||
| ## Example output: | ||
| ``` | ||
